Car dies when I come to a stop

The electrical connection on the EGR valve is the EGR valve position sensor. It provides feedback to the computer to let it know that it's opening and closing when the computer opens and closes the EGR vacuum regulator solenoid. The EGR valve is what allows exhaust back into the intake to be burned to reduce emissions. This also helps keep combustion chamber temps down to reduce problems with detonation and reduce NOx emissions.

Where are you at this point? You have the vacuum line disconnected, but the electrical connector still connected? If that's not where you are, that's where you should be. The electrical connection doesn't control the opening and closing of the EGR valve, but the absence of its signal could cause problems.

If you don't want to spend the money on replacing the EGR valve (I think I may have one that I can send you, by the way), you could just fabricate a plate to mount between the EGR valve and the EGR spacer. This would block the exhaust completely and fix your problem if the EGR valve is sticking open a little bit. You could do this until you prove it's the EGR valve causing the problem and then know that money spent on a new EGR valve is worth it.
